To @ZZ whom t may concer/n: n

Be it known that I, JOSEPH B..IIOLDEN, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following'is a specification.

My invention relates to typewriting or like machines, and more particularly to means for clamping labels or cards to the surface of the platen.

The main object of the invention, generally stated, is to provide simple and efiicient means of the character specified which may be easily assembled on the platen; which may be manufactured at small cost, and which does not interfere with the use of the machine for ordinary work when the clamping means are not to be used.

To'the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set i forth in the following description and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the diHerent views,

Figure l is an enlarged longitudinal sectional view of a platen equipped with the clamping means of my invention; the section being taken on the line 1--1 of Figure 2 and looking in the direction of the arrows at said line.

Figure 2 is a transverse sectional view of the same taken onthe line 2 2 0f Figure 1 and looking in the direction of the arrows at said line.

Figure 3 is a right-hand end view of the platen with parts broken away.

Figure 5 is l a detail fragmentary sec-` tional view'taken on the line 5-5 of Figure 3 and looking in the direction of the arrows at said line; the view showing the clamp controlling lever and some of the associated parts. y

Figure 6 is an end view of the clamp controlling lever; and

Figure 7 is a detail fragmentary perspective view of the clamp supportin vrod and one of the clamping fingers carrie thereb'yu 1923. serial No. 632,235.

I have shown the devices of my invention in the present instance employed on the platen of a Remington portable machine, though they are capable of application to the platens of typewriting and like machines generally, and without interfering with the employment of the machines for ordinary purposes when thev clamping means are not in use.

The cylindrical platen is designated as a whole by the reference numeral 1, and comprises an outer shell 2 of rubber or like material, and the outer facel of which forms a contact surface which supports the worky sheet and on which'a label or card is adapted to be clamped. The shell 2 is fixedvto an inner shell 3, preferably made of metal and perforated at different points in the length thereof, as indicated at 4C.. The shell 3 at one end' has a platen ,headv 5 secured thereto byscrews 6, whereas a second platen head 7 is secured to the opposite end of the shell 3 by screws 8. The platen head 5 has arcentral bearing opening 9 toyreceive the, usual platen shaft or spindle (not shown) that also is received in a central bearing opening 10 in a capped bushingA 11 secured by screws A12 to the platen *head 7 i A line '5. An of-centered tapered b'earing'opening 15, circular in cross-section, is formed inthe platen head 5, and the axisof such' opening extends yparallel with y the yaxis of the platen'. Y l

A cylindrical .clamp supportingkrodl 16 has one end seatedy and supportedinv the bearing opening 15. vThis 'rod is maintained wholly within the platen .and extends longitudinally thereof substantially parallel with the axis, oftheplaten. The opposite or free end portion. of the rod is preferably slabbed off on` one side,l to provide` a halfround reduced en d portion 17. This reducedy end portion conforms substantially in spacing wheel `13 vin the p'resent instance lis secured by screws 14 tothe platen head cross section to' a. seat 18 (see Fig. 46) of `socket 19 to enable the rod and lever 20 to assume varyingv angular relations, and permit'such parts to be readily assembled and enable a detachment ofthe lever from the y rod to be effected when desired. The conhowever, that the lever supports the freel nec-tion between the rod and leverfis such,

the inside ofthe platen to the outside thereof near one entLpassing through the slot 2l and throi-igh ,a registering open-ended i slot inthe s ell 3. The outer end of the lever 20 is yprovided with a finger piece 25, which preferably ,does not extend beyond an extension ot the outer surface of the Pieten lThe lever eed ite insel rieee there- Afore, will not interfere with a :work sheet -Which.,may overlap the` right-hand end of the pla-ten. A depending pin 26 is `riveted to the under side of the finger piece 25, and .extends into a coiledexpansion spring 27 received in an .opening 28 in the platen head 7.; the spring bearing at its inner end againstthe rbushing ,11. which vforms .the bottom Wall of the .opening 28;

' A groove y29 is provided in, and extends longitudinally of, the rod 16y and in this `cove islseated and secured the foot piece 3,0 of each of the vvireacla-mping fingers.`

Each ,clamping tinger isixed to the rod as, for .enamplegby soldering lts foot piece ian the groove '21.9.' Each clamping finger is formed with outwardly extending stem *31 that bent orward at `right angles kto theleifgth the stem at the outer free end portion thereof, Ato form a clamping or engaging member 52.` desired number loflampi'ngfingers be provided, three being shown in the Apresent instance nea-r the iight-#heedyeed' metier et the. pieten, -es ehewe- Fis f1.4 Yl Eeeh demping finger extends-through an opening/e in the-innerv Shell@ eed through e reetahgeler registereeeereneie' '33 in the enter shell 2 Eeeh epenreie eleeeh dmeneiee in ereee Section, .ee tereeeive the eeeeeeted elemping member y32 and Ypermit itI to imove theret-hieushybet Suhetahtelv ll the Grenier: at the ysurace of the platen when the part 32'is positioned its opening` as `indicated in Figs, l and 2.

It will be understood, there fore, that when the clamp is not in use, it doesl not interferein any manner Withthe use of the machine for writing in the ordinary manner on `a work sheet. c.

In order to usetheiclamp it is merely necessary to depress the linger piece 25 against 'the force of the spring` 27. They leffect ,of this is to move the inner end of the leveroiitvvardly away from the axis ci Athe platen, and swing the rod 16 laterallyby pivotal movement aioiindthe point of `its support.` This outward swinging movement.

of lthe rod Causes the engaging members 32 of the clamping fingers to be moved out- Wardly beyond. the `outer surface v0:1? ythe platen. fWhile thepartsare maintainedl in thisfpositon, the leading edge 'of the label` or cardl: is introdneed beneath the mein.

The shell 3 at this point therefore acts as a stop to limit the motion of the `lever under the action of its-spring 27, and normally maintains the parts in the position shown in Figs. l and 5.

From the foregoingdescription it will be understood that I have provided simple, inexpensive and effective label or card clamping means that may be readily assembled on the platen, and which when not in use does not interfere with the employment of the machine for ordinary work.

It will be observed, moreover, that by merely removing the shaft or spindle of the ordinary platen, 'such' platen'may be readily replaced by one equipped with the label clamping means of my invention; such replacement being easily and quickly effected.

Various changes may be vmade without departing from my invention as it is defined in the accompanying claims.

`What I claim as new and desire to secure by Letters Patent, is
